Windows

[alexconrad]

Due to an undisclosed need, i had to run pretty on Windows.
When running pretty i got:

ERROR: PHP CodeSniffer does not seem to be installed because the 'phpcs' program cannot be found.

It was strange because i had phpcs installed and i could run it just fine. After looking trough this code i noticed that the error message comes from:

function commandExists($command)
{
    $return = shell_exec('which ' . escapeshellarg($command));
    return !empty($return);
}

which cannot be installed on Windows, so i just changed the above code to

function commandExists($command)
{
   return true;
}

And poof everthing started working just fine :)
Hope this will help somebody else.
